Application filed November 19, 1908. Serial lie-$68,480.

To all whom itmay concern: j Be it known that I, WARREN H.IWALKER,acitizen of the United States, residing at Racine, in the county ofRacine and-State of Wisconsin, have invented certain new and -useful 1mrevements in Rail-Anchors, of

which the ollowing is a specification.

My invention pertains in general to rail anchors or: anti-creepmg devces, the pr mal pal object of whichis to provide means which willautomatically rip or grasp a rail and as therail has a ten ency to creepthe device will automatically increase its grip upon the base ofthe railand thereby prevent the. creeping or longitudinal movement at which theawsare secured to the' lever beingso arranged as to cause thejaws tohave an opening or closing movein'ent according to the movement of saidlever.

A further object of' the invention isto providemeans wher byothe anchorwill not a other causes. i u

, Further advantages will appcar' throughout the specification andclaims and are lose itsgrip upon the haseof the rail if it so happensthat a backward movement. of the rai occu'rslrelative to the directionof travel, due to the contraction of therail or shown in the drawings inwhich i E1 re 11s a perspective view of my device n attached position.Fig 2 is a top plan view. of Fig. 1, the devipe bein shown in openposition by dotted lmes; igs3 is an enlarged detailed-end viewof Fig. .2with. Fig. 4- is a perspective partially closed,-

Referring now, more particularly to the drawing, 5 representsgas a wholea. rail having the usual tread (land base flanges 7 and- 7,thetwo'flanges constituting the base but.

herem given separate terms for a better explanation of the operation ofthe device as applied thereto.

8 1s a railroad tieof the ordinary construction and it is to beunderstood that the direction of travel over the rail 5 is in thedirection of the arrow, as shown in jFi'gsdl The jaws are provided'withhoolted or curved ends 13 adapted to engage the -marginal' edges ofthe flanges 7 and 7. The in- .ner ends of said jaws are provided withpivot pinsj14 and 14', which may be formed mtegral with the'respectivejaws and-adapt ed to extend through suitable apertures 1-5 .formed insaid base late 11. "Said pivot.

pins are preferably ormecl integral with the jaw members, but it ispbvious ofcourse that they" might be formed. separate therefrom andsccnred 'theretmor that they might be formed inte ralwith the base'plate'or separate thereiiom and secured thereto.

The location ofthe pivot. points upon the base member 11 forms a' veryessent al part; of the invention in that they-are so arranged, when intransverse alinement relative to-the rail, that thejaws will be openedthe widest. and as the pivot points applroachlongitudinal alinementrelative tot the jaws intodiiferent parallel planes, they will have .aclamping movement according to the extent of the movem'entof the lever.

Tn the preferred form of construction, when the jaws are pivoted to theplate and are in alinement, the lever will be tang'em tially disposedrelative to. the'jaw 12; and it is in this position tha't the jaws areopened the widest and there is a sufiicient margin between thecurved-ends 1?; of the jaws to perniit them to pass upon either side ofthe ing the pressure of the lever arm' against the.

the, which is of course a fixed point, the base end 11 of the leverwill-cause a move ment of the pivot ins on said base relative to therail so as to rin one jaw in advance of the other jaw, and fore thepivot pins e rail, bringing are in longitudinal alinement relative tothe 1 jaw and the base, a spacer u TL" the mil base, 7

As means "for preventing the from loosening when in their grip-pinposition, due to any contraction oithe rnii or vibrn-- tion thereof lprovide ratchet feces 1.6 and 16 upon the oppositely disposed feces 'oione of the jaw members and the base memher, the teeth of said ratcbetsbeing oppositely arranged and a spring washer l7, having oppositely bentends, is adapted to surround one of the'pivots and the curved endsthereof adnpted-tQ-cngngc the ratchet teeth. It can thereforebje rendilseen that when the device is zippliedto rail and the lever moved so asto turn the lever member relay tive to the jaw, the turned end of thewasher that engages the teeth formed. or. the base Will advancesuccessively from tooth to tooth until the device is in locked position,whereupon said spring wnshe' will prevent the jaw from backing up andopening where by the device will drop from the rail base.

When the rutchets are placed between a 18 is employed that is adapted tosurround the other pivot pins and cotter pins 19 adapted to extendthrough suitable apertures tne ends of said'pivot pins whereby the leverroenr her is firmly secured to said pivot pins.

It is of course obvious that instead of placing the rstcliets in theposition shown, the base plate might be in Contact with the jaw memberand one of the ratchet faces formed upon the under side. of the baseplate, nnd the-other ratchet members secured to, the pivotpin at itslower end with the spring washer interposed between the feces of saidratohcts suitable means, however, be ing provided for preventing therotation of the ratchet member t] is secured. tothe pivot pin, In thisconstructirui the spacer 18 would not be'einployed.

rail the iirroiv reep oo'tn s des able manner or suitableretninii'igmeans for preventing the movement thereof, the

construction shown herein being only the preferredembodiment tle3ce,'c-.nd,

crease of I therefore, Without confining myself to the particularconstruction,

I claim:

l. A rail anchor comprising n pair of jaws and it lever member to whichone of said jaws is pivoted, substantially :15 described.

2. A rail anchor comprising :1 pair of jaws and a lever member to whichsaid jaws are independently pivoted, substantially as described.

A rail anchor comprisiinf a lovcrmcmbcr adapted to engage :1 tie or thelike and having a pair of jaws secured thereto and adopted to grip thebase of a. rail upon opposite sides thereof; one of said jaws beingmovable relative to said lever member, as and for the purposesdescribed.

A rail anchor comprising :1 pair of jaws, a lever member to which saidjaws arc pivoted and means on one of said jaws for preventing therotation thereof when in set position, substantially ns described.

In rail anchor, the combination of n.

lever inen'iber adapted to engage :1 tie at one end thereof and providedwith a base plate, :1 pair oi jaws pivoted to said base plate and havingcurved ends adapted to grip the n'mrginel edges of a rail base. said.beng arranged in longitudinal nlincment when in open position andadapted to be moved. into different parallel planes upon a movement ofsaid lever member, for the purposes described.

G. A rail anchor comprising; a lever member nnd :rpair of jaw memberspivotnlly mounted thereon, whereby the-jaw members will be moved intodiil'erent parallel planes upon a movement of said lever member,substantially as described.

Y; In a rail anchor, the combination of :1. pair of jaws adapted toengage the marginal edges of {L rail base, a lever member to which suchof said jaws is independently pivoted,

and means upon one of said. jaws for preventing a backward pivotalmovement of onoof said jaws relati e to said lever when said jaws are inn grioping position, subst :1 ntinlly as described.
